In ICD10- what dx code would you use when the pt is PCOS but is starting infertility treatment needing cycle management of her ovaries with follicular u/s's and labs using Clomid and possibly heading towards have an AI? ICD10 has an excludes 1 note under the heading of infertility for the PCOS. Should I use only the unspecified infertility code of N97.9 or use only the PCOS code alone?
